Answer:
C. The Council of Constance appointed a new pope.
Step-by-step explanation:
The Great Schism was an important cultural event that defined the 14th century. It was mainly a conflict between the monarchy of King Philip IV of France and the Catholic Church led by Pope Boniface VII. Among many reasons, the King was unhappy with the amount of power the church held and how it used it to collect taxes. The conflict was ended in the early 1400s when the Council of Constance elected a new pope, making this the only reason listed that wasn't a cause of the event.
